Oil bath use method and precautions

Electrothermal constant temperature oil baths are widely used for distillation, drying, concentration and impregnation of chemicals or biological products. It is an ideal tool for laboratory testers in environmental protection, scientific research, health, epidemic prevention, petroleum, metallurgy, chemical, medical and other institutions.

How to use the oil bath:

1. This instrument uses 220V AC voltage. Please make sure that the rated current of the power socket is not less than 15A before use and has a safety grounding device.

2. When using, you must first add oil to the pot to at least flood the insulation board.

First, turn on the point source. After about one minute, the red number on the meter will display 400, and the lower row will be 0.0. After 30 seconds of rest, the upper row will display the actual water temperature. Press â†—â†˜ /SET button, the upper row will display SP, press â–² Or â–¼ to make the lower row display the desired set temperature. Press â†—â†˜ /SET button, the upper display will display ST, and still press â†—â†˜ /SET to return to the upper row to display the actual temperature. At this point, after a few seconds, the smart watch begins to remember the work.

If you want to change the parameters of the smart meter, such as resetting the higher temperature (or the original set temperature error is too large), press â†—â†˜ /SET button, the upper display shows SP, press â–² or â–¼ to make the lower row Displayed as the desired temperature, press â†—â†˜ /SET again, the upper display shows ST, still press â†—â†˜ /SET, the upper display shows the actual temperature. At this time, press and hold â†—â†˜ /AT button for 20 seconds, the RUN light will flash, the meter will start self-tuning, wait for automatic back and forth (refer to stop heating when the temperature is automatically raised to the set temperature, and start heating when it is lower than the set temperature) After the second self-adjustment, the RUN light is off, and the instrument also obtains a set of parameters that can never overcome the over-temperature.

Precautions for the use of oil bath:

1. Please read the instructions carefully before using the instrument.

2. In order to ensure safety, please connect the ground wire when using.

3: It is strictly forbidden to add oil and dry.

4, the oil level can not be too high, to prevent spillage caused by experimental errors

5 When not working, the power should be cut off to avoid accidents.

6. In order to extend the service life of the instrument, please be careful not to get moisture inside the control box to prevent leakage.

7. The instrument is over one-and-a-half-year warranty from the date of delivery (the cost of the work is caused by improper or improper use), and lifetime maintenance.

8. At the end of use, pour out the oil, wipe it with a dry cloth, and place it in a dry and ventilated place.
